FIG. 3 is a perspective viewillustrating the assembly state of a disc assembly in accordance withthe embodiment, FIG. 4 is a front view of the disc assembly shown inFIG. 3, FIG. 5 is a longitudinal-sectional view of the disc assemblyshown in FIG. 3, and FIG. 6 is an exploded perspective view of the discassembly shown in FIG. 3.

As shown in FIGS. 3 to 6, in the air cleaning humidifier 1 in accordancewith this embodiment, the disc assembly 30 is disposed to surround theair blower fan 42 such that a center A of rotation of the disc assembly30 is approximately the same as a center B of rotation of the air blowerfan 42. Further, the disc assembly 30 is accommodated in the main bodyframe 11 such that the disc assembly 30 is overlapped with the airblower fan 42.

The disc assembly 30 includes a disc member 31 assembled by stackingdiscs, a first plate member 32 disposed at one side of the disc member31, and a second plate member 33 disposed at the other side of the discmember 31.

The disc member 31 in accordance with this embodiment may serve as ahumidification element, and be obtained by stacking several ring-shapeddiscs. The disc member 31 is approximately ring-shaped, and is providedwith assembly parts 100 obtained by partially cutting the disc member 31so as to be assembled with the first plate member 32 and the secondplate member 33.

The assembly parts 100 may include at least one of recess parts 110,each of which is indented on the edge of the disc member 31, and holeparts 120, each of which is formed at one position on the surface of thedisc member 31.

If the assembly parts 100, such as the recess parts 110 or the holeparts 120, are formed on the ring-shaped disc member 31, when severaldisc members 31 are stacked, alignment for stacking of the disc members31 may be easy, and when the first plate member 32 is inserted into thedisc member 31, the first plate member 32 and the disc member 31 may besimply assembled without delicate manipulation.

Fixing members 200 are respectively connected to the recess parts 110and the hole parts 120. These fixing members 200 will be describedlater.

Although the disc member 31 formed by stacking several ring-shaped discsis illustrated in the drawings, an integral disc, which is capable ofholding water, may be used as the disc member 31 so long as the discmember 31 serves as a humidification element.

Further, although the disc member 31 provided with five recess parts 110and one hole part 120 is illustrated in the drawings, the disc member 31may be provided with only the recess parts 110 or only the hole parts120, or one or plural recess parts 110 and one or plural hole parts 120according to shapes of the disc member 31.

The first plate member 32 is disposed at one side of the disc member 31on the main body frame 11 adjoining the front cover 12. The first platemember 32 includes a ring part 32 a forming the ring-shaped externalappearance of the first plate member 32, an opening 32 b formed at thecenter of the ring part 32 a, and a gear part 32 c formed along thecircumference of the ring part 32 a.

The opening 32 b having a greater diameter than the outer diameter ofthe air blower fan 42 is formed at the center of the ring part 32 a. Theair blower fan 42 is inserted into the opening 32 b so as to beconnected to the main body frame 11.

Further, the gear part 32 c is connected to a driving unit 70, whichwill be described later. The gear part 32 c receives rotary forcetransmitted from the driving unit 70, and then generates rotary force ofthe disc assembly 30.

The fixing members 200, which respectively pass through the assemblyparts 100 of the disc member 31, are formed on the first plate member32. The fixing members 200 may include at least one of first fixingmembers 210 inserted into the recess parts 110 of the disc member 31,and second fixing members 220 inserted into the hole parts 120 of thedisc member 31.

Here, the fixing members 200 may be formed integrally with the firstplate member 32, or may be manufactured separately from the first platemember 32 and then be connected to the first plate member 32.

The second plate member 33 is disposed at the other side of the discmember 31 on the main body frame 11 adjoining the rear cover 13. Thesecond plate member 33 includes screw holes 33 a formed at positionscorresponding to the assembly parts 110 of the disc member 31 and thefixing members 200 of the first plate member 32. The screw holes 33 aserve as intermediates during a process of connecting screws 34 to thefixing members 200.

FIG. 7 is an enlarged view of a portion of the rear surface of the firstplate member shown in FIG. 6.

As shown in FIGS. 6 and 7, the first fixing members 210 are protrudedfrom the edge of the ring part 32 a of the first plate member 32 so asto be connected to the recess parts 110 of the disc member 31. The firstfixing members 210 are inserted into the recess parts 110 of the discmember 31, and thus serve to maintain the assembly shape of the discassembly 30.

Each of the first fixing members 210 includes a first protrusion part211 protruded in the stacking direction of the disc member 31, a firstscrew connection part 212 formed through the first protrusion part 211such that the screw 34 is connected thereto, and a first water storagepart 213 formed by cutting a part of the first protrusion part 211.

The first protrusion part 211 has a rod shape protruded to a designatedlength, and is inserted into the recess part 110 of the disc member 31.The length of the first protrusion part 211 is approximately equal tothe stacking thickness of the disc member 31.

The first water storage part 213 is a hollow structure formed in thefirst protrusion part 211 by cutting the part of the first protrusionpart 211. The first water storage part 213 includes a water storagespace 213 a formed within the first protrusion part 211, and an entranceand exit hole 213 b, through which water contained in tub 20 enters thewater storage space 213 a and then is discharged at a designated heightto the outside of the water storage space 213 a.

The entrance and exit hole 213 b is formed to have a lengthcorresponding to that of the recess part 110 by partially cutting thefirst protrusion part 211, and may have various shapes. That is, theentrance and exit hole 213 b of the first water storage part 213 inaccordance with this embodiment is not limited to a rectangular shapeformed by partially cutting the rod-shaped first protrusion part 211, asshown in FIGS. 6 and 7.

Here, the shape of the entrance and exit hole 213 b depends on at whichheight of the air cleaning humidifier 1 is water stored in the waterstorage space 213 discharged to the disc member 31 through the entranceand exit hole 213 b during a process of rotating the disc assembly 30.

That is, if the entrance and exit hole 213 b is formed in a shape, asshown in FIG. 8, water stored in the water storage space 213 a from theuppermost region of the air cleaning humidifier 1 is discharged to thedisc member 31. Further, if the entrance and exit hole 213 b is formedin a shape, as shown in FIG. 9, water stored in the water storage space213 a from a region located at a lower position that the uppermostregion of the air cleaning humidifier 1 is discharged to the disc member31.

Therefore, the entrance and exit hole 213 b is provided in variousshapes according to at which position or height of the air cleaninghumidifier 1 does the disc member 31 hold little water, thereby beingcapable of discharging water to the disc member 31.

In the process of rotating the disc assembly 30, when the first waterstorage part 213 is soaked in water contained in the tub 20, the waterin the tub 20 enters the first water storage part 213 through theentrance and exit hole 213 b, and when the first water storage part 213is located at more than a designated height, the water in the firstwater storage part 213 is discharged to the disc member 31 through theentrance and exit hole 213 b and thus soaks the surface of the dry discmember 31 again so as to increase a humidify amount.

Although five fixing members 210 are protruded from the edge of the ringpart 32 a of the first plate member 32 so as to be connected to the fiverecess parts 110 formed on the disc member 31, the number of the fixingmembers 210 is not limited thereto but may be various.

Further, as shown in FIGS. 6 and 10, the second fixing members 220 areprotruded from the surface of the ring part 32 a of the first platemember 32 so as to be connected to the hole parts 120 of the disc member31. The second fixing members 220 are protruded in the stackingdirection of the disc member 31 and pass through the hole parts 120, andthus serve to fix the disc member 31.

Each of the second fixing members 220 includes a second protrusion part221 protruded in the stacking direction of the disc member 31, a secondscrew connection part 222 formed through the second protrusion part 221such that the screw 34 is connected thereto, and a second water storagepart 223 to store a part of water contained in the tub 20.

The second protrusion part 221 has a rod shape protruded to a designatedlength, and is inserted into the hole part 120 of the disc member 31.The length of the second protrusion part 221 is approximately equal tothe stacking thickness of the disc member 31.

The second water storage part 223 is a hollow structure formed in thesecond protrusion part 221 by partially cutting the second protrusionpart 221, in the same manner as the first water storage part 213.Further, the second water storage part 223 includes a water storagespace 223 a formed within the second protrusion part 221, and anentrance and exit hole 223 b, through which water stored in tub 20enters the water storage space 223 a and then is discharged at adesignated height to the outside of the water storage space 223 a.

Therefore, in the process of rotating the disc assembly 30, when thesecond water storage part 223 is soaked in water contained in the tub20, the water in the tub 20 enters the second water storage part 223through the entrance and exit hole 223 b, and when the second waterstorage part 223 is located at a designated height, the water in thesecond water storage part 223 is discharged to the disc member 31through the entrance and exit hole 223 b.

However, although the drawings illustrate that both the first and secondfixing members 210 and 220 respectively include the first and secondwater storage parts 213 and 223, the first fixing members 210 mayrespectively include only the first protrusions 211 without the firstwater storage part 213, and the second fixing members 220 mayrespectively include only the second protrusions 221 without the secondwater storage part 223.

On the other hand, although the drawings illustrate that the fixingmembers 200 are formed on the first plate member 32 and then arescrew-connected to the second plate member 33, the fixing members 200may be formed on the second plate member 33 and then be screw-connectedto the first plate member 32.

Further, spacers may be formed between the disc assembly 30 and thefirst plate member 32 and between the disc assembly 30 and the secondplate member 33, thus being capable of adjusting an interval between thedisc assembly 30 and the first plate member 32 and an interval betweenthe disc assembly 30 and the second plate member 33.

The above-described disc assembly 30 is connected to the driving unit 70to generate rotary force of the disc assembly 30. The driving unit 70includes a driving motor and a driving gear, and the driving gear isconnected to the gear part 32 c of the first plate member 32.

The driving force of the driving unit 70 is transmitted to the discassembly 30 by engaging the driving gear of the driving unit 70 with thegear part 32 c of the first plate member 32.

The driving gear may be located below the center A of rotation of thedisc assembly 30. Because the above position of the driving gearprevents interference of the disc assembly 30 with the driving unit 70,when the disc assembly 30 is installed in the air cleaning humidifier 1or is separated from the air cleaning humidifier 1.

Further, support members 80 to support the disc assembly 30 may beprovided in the tub 20. The support members 80 may be detachablydisposed at both sides of the inside of the tub 20. The support members80 are rotatably provided, and serve to guide the disc assembly 30 suchthat the disc assembly 30 is more stably rotated by the driving gear aswell as to support the disc assembly 30.

Hereinafter, with reference to FIGS. 2, 4, 6, and 8, operations of theair cleaning humidifier and the disc assembly thereof in accordance withthe embodiment will be described.

First, water stored in the water tank 50 of the air cleaning humidifier1 is supplied to the tub 20. The water supplied from the water tank 50is stored in the water containing part 21 via the water supply part 22.Here, the amount of the water in the water containing part 21 may beadjusted such that the water reaches a designated water level 21 a.Further, a part of the ring-shaped disc assembly 30 is located under thewater level 21 a in the tub 21, and thus is soaked in the water in thetub 21.

When a user selects an air cleaning and humidification mode through thecontrol part 12 a, the air blower fan 42 and the disc assembly 30 aresimultaneously driven, and cleaned air is discharged from the airdischarge holes 14 c via the disc assembly 30 to the outside.

Now, a process of performing the air cleaning and humidification modewill be described in detail. The driving force generated from thedriving unit 70 is transmitted from the driving gear 72 to the discassembly 30, and thus the disc assembly 30 is rotated.

Further, since the air blower fan 42 is inserted into the opening 32 bof the first plate member 32, the disc assembly 30 is rotated around theair blower fan 42. The rotation of the air blower fan 42 generates anair current in the air cleaning humidifier 1. Through such an aircurrent, air is inhaled into the air cleaning humidifier 1 through theair suction holes 13 a formed through the rear surface of the aircleaning humidifier 1, is inhaled to the air blower fan 42 via thefilter 60, passes through the disc assembly 30, and then is dischargedto the outside.

That is, the air blower fan 42 and the disc member 31 are overlappedwith each other, and thus the air current discharged from the air blowerfan 42 is blown to the disc assembly 30. While the blown air passesthrough the disc member 31, water held by the disc member 31 isevaporated. The obtained humidified air is discharged from the main body10 to the outside through the air discharge holes 14 c.

At this time, when the disc assembly 30 is rotated, water contained inthe tub 20 is lifted up by the first water storage parts 213 of thefirst fixing members 210. Then, when one first water storage parts 213is located at a designated height, water stored in the water storagespace 213 a is discharged to the disc member 31 through the entrance andexit hole 213 b, and thus allows the disc member 31 to hold a largeramount of water.

Therefore, since the disc member 31 has a more improved moisturecontaining capacity during air humidification caused by the rotation ofthe disc assembly 30, more effective air humidification may be achieved.

As is apparent from the above description, in an air cleaning humidifier1 and a disc assembly 30 thereof in accordance with one embodiment ofthe present invention, fixing members 200 inserted into assembly parts100 of a disc member 31 to maintain an assembly shape of the discassembly 30 respectively include water storage parts to store water soas to discharge water to the disc member 31, thereby more effectivelyachieving air humidification.
